* 1. #701 ~ #708:The measured value of channel 1~l 8. The unit is determined according to the
input type (#901 ~ #908). When the mode is Celsius, the unit is 0.1 ℃ ; when the mode is
Fahrenheit, the unit is 0.1℉.
* 2. #709 ~ #716:Heating side control output value MV; #717 ~ #724: cooling hot side control
output value MV; The control output value of the channel obtained by the control algorithm.
* 3. #725 ~ #732: Each channel Multi-step setting executes the current segment. The segment
number being executed when multiple segment Settings are displayed. 0: indicates that the
execution state is not set in multiple segments or that multiple segments are completed.
* 4. #733: Output status of refrigeration end. Bit0 corresponds to the output state of the
refrigeration end of channel 1, Bit1 corresponds to the output state of the refrigeration end of
channel 2, and so on. When is 1, the output of the refrigeration end is effective; when is 0, the
output of the refrigeration end is invalid.
* 5. The failure status information of #735 is shown in table 1-6
